New Chemicals Added to Domestic Substances List

Summary#

This is Order 2023-87-08-01 Amending the Domestic Substances List under the Canadian Environmental Protection Act, 1999. It adds several chemicals (listed by CAS number and by polymer descriptions) to the federal Domestic Substances List. The order was registered on July 21, 2023 and published in the Canada Gazette on August 2, 2023.

What it does#

• Adds these CAS numbers to Part 1 of the Domestic Substances List:
  • 6920-22-5
  • 18297-63-7
  • 51728-26-8
  • 71868-15-0
  • 141091-65-8
  • 2102038-87-7
  • 2135769-70-7
  • 2803749-89-3
• Adds these two polymer descriptions to Part 3 of the List:
  • Poly(oxyalkanediyl), α-hydro-ω-hydroxy-, polymer with methylenebis[isocyanatocycloalkane], alkenenoic acid, hydroxy-, alkyl ester-blocked
  • Fatty acids, polymers with polyethylene glycol and succinic anhydride polyalkylene derivs.
• Notes from the order:
  • The Ministers (Environment and Health) were shown information that the substances had been made in or imported into Canada above the reporting threshold in the New Substances Notification Regulations (Chemicals and Polymers).
  • The government’s assessment period for that information had ended and no special conditions were in effect.
• The order takes effect on the day it was registered: July 21, 2023.

Who's affected#

• Companies that manufacture or import the listed substances into Canada.
• Businesses that use those specific chemicals in products or processes (industrial suppliers, formulators, processors).
• Regulators at Environment and Climate Change Canada and Health Canada, since they handle substance information and assessments.
• It is not clear from the order whether consumer-facing products or the general public will notice any immediate change.

Why it matters#

• Being added to the Domestic Substances List means these chemical identifiers are now recorded by the federal government as substances present in Canada.
• That status changes how the chemicals are tracked and handled under federal chemical rules. In plain terms, firms and regulators treat them differently than substances not on the list.
• If you work with chemicals, this can affect reporting and regulatory steps your company must follow. If you are a member of the public, the change mainly affects how those substances are managed by government and industry rather than creating any direct new requirements for consumers.
